“…Diversos autores han desarrollado técnicas y algoritmos de control de transferencia metálica en soldadura [6][7][8][9], lo que ha implicado el monitoreo de algunos parámetros que fueron utilizados para cerrar el lazo de control. La fusión de estos sistemas de control y monitoreo ha dado origen a los sistemas de evaluación de calidad y corrección de perturbaciones y que de acuerdo a la complejidad de las operaciones que desempeñan (ver figura 1), estos sistemas pueden clasificarse en tres niveles [10]. En el primer nivel es posible detectar soldaduras defectuosas automáticamente durante la producción a partir del monitoreo de la tensión y/o la corriente de soldadura.…”

“…This fact make eases the installation of the sensor and reduces the possibility to alter the electric parameters of the welding process and reduces the influence of the electromagnetic field on the acoustic sensor. It can be found in literature some acoustical monitoring systems for GMA welding process, but it not yet are used in the industry (Mansoor, 1999;Grad, 2004;Poopat, 2006;Cayo, 2007). In the present work was developed a weld defect detection technique based on the welding stability evaluation through sound produced by welding electric arc.…”
